Recently I was looking for a way to set DefaultInboundAction and DefaultOutboundAction for Windows firewall
First I tried 'netsh.exe advfirewall set allprofiles firewallpolicy blockinbound,blockoutbound'
However, it turns out group policy overrides these settings.
I then went looking for a way to set the Firewall group policy and the best I could find was making a policy and copying it to the system32\grouppolicy folder and then running gpupdate.exe /force
Instead of relying on such a rigid procedure I instead decided to parse the Registry.pol file and change the values within.
This code has only been tested on W7x64
The example as supplied sets the domain profile firewall off the sets it back to the previous settings after you click the message box
There are several options:
Func SetGroupPolicy_Firewall($iSetting, $iValue, $sPath, $sProfile = "")
Setting=0 Enable disable firewall , $iValue=0 Disable, $iValue=1 Enable
Setting=1 DefaultInboundAction, $iValue=0 Allow, $iValue=1 Block
Setting=2 DefaultOutboundAction, $iValue=0 Allow, $iValue=1 Block
Profile ="" SET ALL PROFILES
The profile can also be defined
Beware $iValue is only configured for 0 and 1 values there are a few more options on the inbound and outbound settings that I haven't given a way to set, so in this case you may need to copy back the registy.pol.bak file to revert to your previous settings
It doesn't seem to have any issues on reverting back to original settings if Block all Exceptions or NotConfigured are set It just won't work which in my case is acceptable
It wouldn't be too hard to add code to make these work as well:
"[SOFTWARE\Policies\Microsoft\WindowsFirewall\DomainProfile" & CHRW(0) & ";DefaultInboundAction" & CHRW(0) & ";" & CHRW(4) & CHRW(0) & ";" & CHRW(4) & CHRW(0) & $iValue & CHRW(0) & "]" ;And Again for: ;[SOFTWARE\Policies\Microsoft\WindowsFirewall\DomainProfile;DoNotAllowExceptions;;;] Do note that these would need to be added for each profile. Domain;Public;Private.
These locations do refer to actual registry locations but I haven't figured out a way to get those to change the group policy.
If you run into problems or make improvements let me know
a backup is saved as C:\Windows\System32\GroupPolicy\Machine\Registry.pol.bak just in case

I'm having a trouble with TCPAccept() on compiled scripts.
This script I made to test:
#include <Debug.au3> _DebugSetup() TCPStartup() $Main = TCPListen("0.0.0.0", 8081) _DebugOut("TCPListen output: " & $Main) While True $ac = TCPAccept($Main) _DebugOut("TCPAccept return: " & $ac) If $ac <> -1 Then _DebugOut("There's someone out here!") TCPSend($ac, "hi") EndIf WEnd Works fine if I run it by pressing F5 on SciTe window.
But if I compile it and then execute the executable file, it does not work. Instead, NetCat tells me that the connection timed out (I've tested other clients as well):
I've checked if the port is really opened, if I really can open it, if there is other software using that port, but everything showed that it should connect.
Btw, netstat -an shows that the port is really listening (when I execute my file). It listens, but does not accept.
I use no antivirus software (I use this Windows installation for coding only) and Windows Firewall is disabled. I've tried, anyway, allowing my exe file on Firewall rules, but it also did not work. Running as administrator also did not help.
I believe it's a Windows (Firewall?) bug rather than an AutoIt bug. How can I manage to solve this?
Thanks in advance.
I dug this UDF out in response to a request in the General Help forum. There is still some tidying to do, but I thought I would post here for anyone that would benefit. All functions have been tested on both XP and Windows 7.
